Life becomes very frustrating when your destination is 20 minutes far but it took you 1 hour to reach there because of traffic jams. Think about the time and amount of fuel getting wasted. According to Harvard Center researchers, in the United States, traffic congestion caused more than 2200 deaths because the patient failed to reach the nearest hospital on time, then there is a loss of economic cost when the drivers are stuck in traffic for 42 hours every year wasting more than 121 billion dollars on time and fuel. This is the data of only 1 country. Think of all the countries in the world, How much fuel and economy is wasted every year? Also, it causes air pollution which is bad for our health and climate. So to solve the real-time problems caused by traffic congestion, the government of Hangzhou city of china with the help of Alibaba Cloud (a cloud computing company) created a system called ET City Brain.
